This unit works great! We had it for a month through hot August month. All the flies & mosquitoes stayed outside, while we kept our back French doors wide open (when we were home). We didn’t have to worry when our party guests, especially the kids, leave the doors wide open. I hate flies so I was happy! We had a carpenter mount a 2x8 wood above the back door, outside underneath patio cover so no rain gets it wet. The 2x8 wood ledge is mounted on the structural wood frame of the house, then mounted the unit’s back brackets onto the ledge. At first the fan was rattling so we shifted it slightly and the noise went away. If unit is not perfectly vertically mounted, then the fan will rattle. Now, it is very smooth and forget to turn unit off cuz it’s so quiet! The air flow is easy to adjust, but we couldn’t figure out how to mount the door switch without tapping into the door frame. We didn’t want to mount onto door frame since we want to keep these expensive French doors unmodified.
